5 wire rectifier.

Guys, I am having charging issues with my XS650 once again. I have replaced the rectifier once before and think I need to do it again. I got to thinking about the Honda rectifier fix that is suggested here and wonder if you thought it would work on the XS. The stock Yammie rec is a 3 wire from the stator plus ground and power.

I queried the guys on the XS site first but nobody replied to me.

Any thoughts?

Thanks, as always, I appreciate any input.

Cheers,
Spyug.
 
They're all the same.

Any Honda one will work, just be careful if you get one of the ones with a "sense" wire.

Also, not all Honda RR are created equal - some are better than others. I like the one I'm using from a 929, but the 600rr f3 or f4 is just as good and also has the pigtail (I can't remember which).
 
I was asking Duanage about one of his RRs for a guys XS650. There may be a problem using them, and i cant remember what he said. May want to check with him first.
 
Ok went back and looked... Its possible the Yammie uses a seperate field coil. Dunno what that means, but he said if thats the case the Honda set up may not work.
 
Ah! Well then i would assume no problems. I dunno all this 'lectrical mumbo jumbo, but gimme some 12/2 or 12/3 and some wirenuts and i'll rewire your house :)
 
Thanks for the info guys. I think you confirmed what i suspected. I'll see if I can come upwith a Honda 5 wire unit from my local used parts guys.

I'll let you know how it works (that is if it works).

Cheers all,
Spyug

No sense wire on my 2004 CBR R/R - just 5 wires; three from stator, plus and negative.
 
Thanks for all the input guys. Another couple of question.

I'm looking through E-bay for a suitable Honda rectifier but all I'm seeing is combination rec/reg s for the more up to date bikes. Are these what you are using?

My XS has individual rec and regulator could I just use the rectifier part and not hook up the regulator if mine is working ok?

Still abit confused.

Cheers all,
Spyug.
 
I'm using the newer style Honda R/R without a sense wire. Why would Honda discontinue the use of a sense wire if it was a required element?

It is not required. If it is connected directly to the battery with no other components connected to that wire, it provides a more accurate voltage refrence to the regulator. If connected on a GS without running a seperate line with a relay, it provides a less accurate voltage refrence.
 
I have a few 5 wire honda RR units that are the same as the 6 wire except they use internal reference. They have the same heatsink and internal diodes as the SH -232 units. If your looking for one I have a few available for 40.00 shipped.

Let me know how long the wires need to be and what kind of connectors the Yamaha has. I have just about any connector you can think of, and we can adapt it.

It's definitely not required. I can't figure out why Honda ever used it...?

I didn't think it was required, just don't understand why some people here talk so favorably about it (I'm more of a mechanical guy than an electrical one).

Question now: I have a 7 wire Honda R/R - three stator wires and two each for + and -. I sent one + to the battery with fuse in line and one to the old Suzuki harness plug for the R/R thus feeding the harness. Is this an okay setup? Received a positive response in another thread but now I'm wondering again.
 
That's exactly how I wired mine.

+#1 to batt + via fuse
+#2 to harness +
-#1 to ground on panel/harness ground
-#2 to batt -

3 stator wires to 3 stator wires


If you look at the Honda schematic the two positives and two negatives are connected together pretty soon after joining the harness, which suggests to me that they are the same. I treated them that way.

the sense wire provides better regulator control. It's not like the RR won't work without it but it enables the RR to respond better to load changes. The main advantage of the Honda RR is it's robustness and oversized heatsink. The OEM and most aftermarket RRs are designed for 300 watts and little more. The Honda RR is rated at 450 watts, a significant improvement.

Some Honda RRs have different bolt hole spacing that makes it harder to adapt to the Suzuki. Others power a field coil arrangement. There are a lot of possiblities, that's for sure. Just be glad we are not at the mercy of the dealers or a single supplier for a critical part for our bikes. Too many times we find a great motorcycle that suffers from a common and expensive problem that gets in the way of enjoying the ride.
